Upgrade: Digital Forensic Investigation & Reporting Service for Admissible Legal Evidence (June 2026)

Replas Co., Ltd. offers a "Digital Forensic Investigation and Report Creation Service" at a level that can be submitted as evidence in court in the event of incidents such as internal misconduct or cyberattacks.

*As of June 2026, the Digital Forensic Investigation and Reports have been fully upgraded.

### Background and Challenges: Risk of Losing Admissibility in In-house Investigations In recent years, digital incidents threatening companies, such as the removal of confidential information by employees, embezzlement, and information leakage due to cyberattacks, have increased rapidly. When these troubles escalate into litigation, data in PCs and servers becomes decisive evidence. However, a challenge for many companies is the difficulty of preserving evidence while maintaining legal validity. If internal staff hastily operate target PCs after an incident is discovered, data timestamps may be updated or logs overwritten, leading to the loss of "legal admissibility (legal legitimacy) in court." To solve these issues, we provide forensic investigations strictly based on legal procedures and reports that are easy for judges and management without specialized knowledge to understand.

### Three Features of This Service 1. **Strict Evidence Preservation Based on Legal Procedures** Using specialized tools, we physically create a clone (duplicate) of data from target PCs and servers. Since no changes are made to the original data, we prove there is no tampering, ensuring legal validity as evidence. 2. **High-Quality Investigation Reports for Immediate Court Use** Instead of listing technical terms unique to digital data, we create logical and persuasive reports that allow lawyers and judges to intuitively understand "when, who, and what was done" in a chronological order. 3. **Recovery of Deleted Data and Thorough In-depth Analysis** We use advanced technology to restore data from intentionally deleted files, concealed logs, and even formatted storage. We comprehensively analyze web browsing history, USB memory connection history, email history, etc., to reveal the full picture of the misconduct.

### Main Anticipated Use Cases * **Investigation of Intentional Data Deletion by Retiring or Former Employees:** Useful in cases where important files were deleted just before retirement. We attempt to restore data even if it was "permanently deleted" from the trash and create detailed reports for damages claims. * **Confirmation of Traces of Unnatural Access or Non-business Use on Weekends/Nights:** We list PC startup/shutdown history and software usage/download history to prove suspicious logs as objective facts.

Replas Co., Ltd. will continue to contribute to reducing legal risks and resolving troubles quickly for companies through this service.
